Title: Compound spring of foaming elastic body and metal coiled spring
Inventor: YOSHIDA HIROSHI
IPC: F16F3/10
Filed: 1985-02-08
Abstract: PURPOSE:To obtain required spring characteristic by burying a metal coiled spring in the wall thickness portion of a foaming elastic cylinder, the outer peripheral surface of which is formed to be a spiral concave-convex surface along the spiral of the coiled spring. CONSTITUTION:A steel spring 1 is solidly buried in the center of the thickness of the wall portion of an independently bubble foaming polyurethane cylinder 2. The outer peripheral surface of the cylinder 2 is formed to be a spiral concave-convex surface along the spiral of the metal coiled spring 1 in such a manner that a portion 4 adjacent to the metal coiled spring 1 is projected outward, and a portion 5 positioned intermediate between upper and lower sides of the metal coiled spring 1s recessed inward. As the middle portion 5 of the cylinder positioned intermediate between upper and lower sides of the stell coiled spring 1 is thin, the amount of deformation is large. As load increases, the portion 5 reaches a limit of elasticity, so that the amount of deformation is lessened to gradually increase a spring constant of the cylinder 2.

Abstract: PURPOSE:To form the electrode of an electronic parts like a piezoelectric parts so as to have a uniform film thickness. CONSTITUTION:A substrate 2 composed of PZT sintered body is subjected to electroless plating, thereby forming electrodes 3, 4 in desired portions of the surface. By electroless plating as the wet system film forming technique, the electrodes 3, 4 of uniform film thickness can be formed in any part of the whole surface of the substrate. Hence it does not occur that the film thickness of the parts where the corner parts 2A, 2B, 2C, 2D of the substrate 2 form shadows becomes thin, as in the case of the conventional sputtering method.

Abstract: PURPOSE: To decrease BOD considerably from waste water contg. thick BOD by specifying the peripheral speed of an axial flow impeller, the clearance between the axial flow impeller and a cylindrical inside cylinder, and the pressure in a pressurized aeration tank, respectively, and performing activated sludge treatment.  
     CONSTITUTION: As a means of making efficiency as high as possible and driving power as small as possible under the conditions of assuring a max. flow rate in a pressure aeration tank 1, an impeller 23 is designed as a high efficiency axial flow pump. Delivery at a large flow rate is accomplished by forming the impeller 23 into a vane type section of the specific velocity expressed by the equationI. If the ratio between the inside diameter (d) of an inside cylinder 19 and  the outside diameter da of the impeller 23 is selected at the equation II, the  amt. of the liquid backflowing through the clearance between the vanes and the  inside cylinder to the inflow side is slight. It is desirable to make the peripheral  speed of the impeller 23 constant in order to unify the flow pattern in the tank  and its adequate range is 8W15m/S.

Title: Hydraulic circuit of construction machine
Inventor: HORII KEIJI
IPC: F15B11/028
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent the protruding drive of a working device, by providing speed-reducing restructures bringing about a larger contracting action than a flow rate-adjusting valve in a pair of supply and discharge hydraulic passages respectively. SOLUTION: When a pilot pressure is actuated in a hydraulic chamber 35U by controlling a pilot valve 35A for rotation of the control valve 35 on a rotary base, the spool 35S transfers to the right side. The hydraulic oil from the pump port 35P flows through the first land R1, a compensator 53, and a contracted part rb of the second land R2 at the left side and it is supplied to the rotary motor through the supply and discharge hydraulic passages 35C. And the return oil from the rotary motor flows into a tank port 35t through the right side supply and discharge passage 35C and the contracted part rb of the right side second land R2. In this way, the fluid forces in respective contracted parts rb of the second land R2 act as shown in the mutually reverse arrow marks (a), (b) and hence, cancel each other.  Since abrupt increase of the pump pressure is restricted on changing over the control valve 35, the protruding drive of the rotary base or the like can be prevented.

Title: Measuring instrument of fine level difference
Inventor: HONMA NORIAKI
IPC: G01B11/22
Filed: 1985-02-08
Abstract: PURPOSE:To measure positional identification on the surface of an object stably and highly accurately by forming a means for perturbing the relative position of convergence position of an optical beam to a sample surface in the optical axis direction and a phase synchronization detecting amplifier. CONSTITUTION:Light projected from an optical source 8 is divided by a beam splitter 11 through a monochrometer 9 and a collimeter optical system 10, condensed by an objective lens 2' and then focused on a position close to the surface of the object 3. The reflected light from the object 3 is condensed by a collector lens 4 through the splitter 11 and converted into an electric signal by a photodetector 6. On the other hand, the wavelength of the light obtained from the monochrometer 9 is swept while being finely varied by the frequency of an oscillator 13, so that the focal distance of the lens 2' is also swept while being finely oscillated in the optical axis direction. The frequency component of the perturbation is detected by the phase detecting amplifier 14 and the zero-cross point of the output signal of the amplifier 14 is detected by a zero- cross point detecting circuit 15. A focal position is found out from the wavelength of the zero-cross point. Thus, the distribution of the focal positions on the surface of the object can be obtained by repeating said procedure.

Abstract: PURPOSE:To enhance reflectivity of non-recording area by providing an optical interference layer having a small extinction coefficient between a recording layer and a reflective layer and making reflectivity of a recording area for playback beam smaller than that of the non-recording area. CONSTITUTION:A recording layer 2, an optical interference layer 3 having a small extinction coefficient, a reflection layer 4 and a protection layer 5 are provided on a substrate 1 and a laser beam (reproducing beam) 6 is then applied, from the side of substrate 1, to non-recording area of a beam recording medium.

This wave 7 passes the interface and is partly reflected at the interface between the layers 2 and 3 to become an amplitude reflection wave 8. Moreover, the beam 6 having passed this interface is reflected at the interface between the layers 3 and 4 to become an amplitude reflection wave 9. The reflection waves 7 to 9 are interfered with each other to become a total reflection wave. The phases of reflection waves 8 and 9 are coincided and optical film thickness of layers 2, 3 are adjusted to use amplification by interference. Thereby, reflectivity of non-recording area can be enhanced.
